AN/TPS-75 Radar System

The AN/TPS-75 Radar System [ "Tipsy 75"] is a mobile, tactical radar system capable of providing radar azimuth, range, height, and Identification Friend or Foe (IFF) information for a 240-nautical-mile area. This deployable/transportable radar system is capable of providing long range radar data to support operations and control of tactical aircraft. The TPS-75 today forms the backbone of the US Air Force Air Defense system. The AN/TPS-75 Radar system provides a "real-time" radar airspace picture and data in support of the battle commander and the Ground Theater Air Control System (GTACS) via radio, telephone, microwave relay, or satellite communications link. The AN/TPS-75 radar system includes the UPX-27 IFF/SIF equipment, Tactical Air Operation Interface Gp OA 9194/TYQ-23(V)2, Modular Control Equipment Interface Group (MIG) and AN/TLQ-32 ARM Decoy.
The AN/TPS-75 is a mobile ground radar set designed to conduct long-range search
and altitude-finding operations simultaneously. Data from the AN/TPS-75 can be
combined with information from other radar to form an integrated picture of the aerial
battlefield for theater commanders. The 729th Air Control Squadron, Hill AFB, Utah,
uses this radar for a variety of missions. The self-contained data gathering system
operates independent of inclement weather and jamming environments and requires only
a 400-Hz power source to operate.

The system weighs about 8,400 pounds. It may be transported via plane, helicopter or
truck. This includes Air Force C-141 Starlifter, C-5 Galaxy, C-17 Globemaster III or
C-130 Hercules aircraft. During daylight hours, a trained six-person crew can assemble
the unit from transport mode to full operation within 90 minutes. A trained crew of nine
can accomplish the same task within 2.5 hours at night. Disassembly of the set can be
done in the same time. The unit's antenna operates from sea level to 10,000 feet in
conditions that include winds up to 52 knots, ice as much as 1.2 radial inches in
thickness, and heat up to 120 degrees Fahrenheit with 95 percent humidity.

Preplanned Product Improvement (P3I) for the AN/TPS-75 Radar include technology and cost risk reductions involving advanced development of a solid state transmitter or the AN/TPS radar are being pursued, in addition to system engineering support to various system program offices.
